Model HP18S16
Wenesco Model HP18S16 is designed for controlled heating of large liquid volumes in industrial, laboratory, and chemical processing applications. The unit supports optional remote digital thermostat control with an external thermocouple immersed directly into the fluid, allowing temperature regulation based on liquid temperature rather than plate surface temperature.
This heating method improves process accuracy and consistency when warming water, chemical blends, or temperature-sensitive materials. Model HP18S16 can heat 20 gallons of water in a covered stock pot from 70°F to 210°F in approximately 2 hours, with most industrial liquids reaching target temperatures faster due to lower specific heat values.

Model HP18S16 will heat 20 gallons of water in a covered stock pot from 70F to 210F in 2 hours
Model HP22S42 will heat 20 gallons from 70F to 210F in 55 minutes.
Due to lower specific heat values, most liquids and blends will heat faster than water
Frequently Asked Questions
What industries use Wenesco round hot plates?
Wenesco round hot plates are commonly used in laboratories, chemical processing, pharmaceutical manufacturing, industrial production, research facilities, and material testing environments where consistent surface heating is required.
What is the benefit of cast iron heated plates?
Cast iron provides excellent heat retention, uniform thermal distribution, and long-term durability under elevated operating temperatures. It also withstands repeated heating cycles in demanding industrial applications.
How does the remote thermostat improve temperature control?
A remote thermostat with an external thermocouple measures the temperature of the fluid or process material directly instead of the plate surface. This improves process accuracy and helps maintain more stable operating temperatures.
Can these hot plates heat large containers or drums?
Yes. Models such as the HP22S36 are specifically designed for heating large vessels, including full 55-gallon drums, stock pots, and industrial processing containers.
Are Wenesco round hot plates suitable for continuous operation?
Wenesco round hot plates are built for industrial-duty performance and long operational life. Their heavy-duty construction and precision temperature controls support continuous heating applications in demanding environments.
